SOAP CAKE.

SPECIFICATION forming part of Letters Patent No. 790,319, dated ay 23, 1905.

i Application filed February 18, 1905. Serial No. 246,352-

To all whom it may concern.-

Be it known that l, LEOPOLD S. SAMUEL, a

citizen of the United States, residing at Newark, in'the county of- Essex and State of New Jersey, have invented certain new and useful Improvements in Soap Cakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention'relates to certain improvements in soap cakes containing layers of compounds, medicaments, or matters other than soap serving to produce other useful effects while the detergent elements of the cake are operating.

The objects of the present invention are to secure a more uniform distribution of the medicament or other non-saponaceous compound throughout the" cake, whereby it will more certainly and efiicaciously contact with the skin in service, to prevent more effectively the formation of unfilled spaces'within the cake, to enable the soap sections of the cake to hold non-soapy matter therebetween and the cake as a whole in condition for service for a longer preliminary period, and to secure other ad vantages and'results, some of which may be,

referred to hereinafter in connection'with the description of the parts.

The invention consists in the improved soap cake and in the arrangements and combinations of parts of the same, ali substantially as 1 will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the figures, Fig-.

' ure is a plan of my improved soap cake.

Fig. 2 is a plan of the inside of one of the sections thereof. Fig. 3 is a section through the shorter axis of the said cake, and Fig. 4 is a side elevation of said cake. In said drawings, 5 6 indicate two saponaceous outer sections of the soap cake,and 7 indicates a compound, composition, or substance 5 which differs materially from the composition of the sections 5 6 in that said composition, compound, or substance contains very little or no saponaceous matter, or, if largely of saponaceous matter, it may be impregnated with a medicament, qualifien or content by which it is given a characteristic materially diflerent in efficiency from the characteristic or characteristics of the sections 5 6.

'The'part 7 may be wholly of one materialwax, for instance-especially if the soap cake is to be used for. certain laundry purposes, or it may be of soap or other vehicle for a medicament, or, and preferably, it may beacreamlike composition containing more or less wellknown matters capable of rendering the skin soft, clear, free from sores, &c., or otherwise in a healthy condition.

To enable the cream-like or other substance to be uniformly and quickly inserted between the sections 5 6, so that no open spaces will be formed due to the entrapping of air, haste of application, or otherwise, I have formed the sections as ill ustrated, the section 6 having male protuberances 8 8 at its inner side, which lie at opposite ends of thelong'er axis of the sections. shallow recesses of a corresponding shape in plan formed in the section 5, as indicated in outline in Fig. 4, and thus the said sections come together at their ends; but intermediate of said ends and at the sides of the protuberances said sections lie apart to form a chamber for the intervening cream substance or other matter. Between said protuberances said cakes are perforated, as at 9', the walls of the perforations being slotted, as at 10, and inwardly fl aring,-as shown clearly in Fig. 3. The surface-walls of the chamber between the sections are also slotted, as at 11,to serve to.in-' crease the strength of union between the united parts. The sections 5 and 6 being thus formed, the same are individually spread with the creamy or plastic mass of matter 7, a

quantity being applied to each of said parts guided and held in proper relation. 'The Said protuberances 8 8 fit neatly into creamy mass is forced into all the'recesses and compacted by pressure, and the surplus matter flows out at the sides and through the perforations, whence it may be quickly removed. I-am thus enabled to quickly obtain within the cake a solid -mass of medicated k matter throughout, which extends outwardly to theperiphery of the cake both at its edge and at the flat center of the sides of the cake, where it is certain to freely contact with the hand in service, and all blow -holes are avoided.

Having thus described the invention, what I claim as new is 1. The improved soap cake herein described, comprising two centrally-perforated sections, onehaving protuberances at the opposite ends of its inner side and the other having shallow recesses to receive said protuberances, and an lntermediate mass of matter extending from the center of the cake to its side peripheral edges and into said perforatlons,

substantially as set forth.

2. The improved soap cake herein described, comprising two sections, one having male protuberances to enter recesses in the other, and each having inwardly-flaring perforations and chambers extending to the edges of the cake and a plastic mass intermediate of said sections extending into said perforations and to the opposite edges of said cake, substantially as set forth.

3. The improved soap cake herein described comprising two sections, one having
